An electron is projected with an initial speed $1\mathrm{.}00{10}^6\frac{(m)}{(s)}$ into the uniform field between the parallel plates in$.$ Assume that the field between the plates is uniform and directed vertically downward and that the field outside the plates is zero. The electron enters the field at a point midway between the plates

B$)$ What is the strength of the electric field

C$)$What is the potential difference between these two plates

D$)$what is the capacitance between these plates?
